Re: [deal.II] Re: Can we say that the higher order method, the more accurate?

Dear Jaekwang, Thanks for your code, I do come with the same problem as yours! After adding a "mapping" to the constructor of the FEFaceValues in my code, the problem solved~ Best, Howe 在 2017年8月10日星期四 UTC+8上午3:26:00，Jaekwang Kim写道： > > Dear Howe > > I have solved this

Dear Jaekwang Have you solved this problem? If yes, Could pls share your solution with us? I am simulating a steady state flow over a cylinder, and the drag/lift coefficient shows an unexpected trend of change as i increase the discretization order and refine the mesh.
